struct FGeometryScriptBakeType_Occlusion : public [FGeometryScriptBakeTypes](API\Plugins\GeometryScriptingCore\GeometryScript\FGeometryScriptBakeTypes)
float
BiasAngle
Angle in degrees from the horizon for occlusion rays for which the contribution is attenuated to reduce faceting artifacts.
float
MaxDistance
Maximum distance for occlusion rays to test for intersections; a value of 0 means infinity
int32
OcclusionRays
Number of occlusion rays per sample
float
SpreadAngle
Maximum spread angle in degrees for occlusion rays; for example, 180 degrees will cover the entire hemisphere whereas 90 degrees will only cover the center of the hemisphere down to 45 degrees from the horizon.
